The hierarchical nature of this taxonomy implies that different levels of resolution are likely to be optimal for different purposes. Our aim was to identify which level of detail is likely to provide optimal validity and explanatory power with regard to relevant clinical variables.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722003324_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services project, we used data from a sample of 2900 psychiatric outpatients to compare different levels from a bass-ackwards model of psychopathology in relation to psychosocial impairment across different domains (global functioning, inability to work, social functioning, suicidal ideation, history of suicide attempts, history of psychiatric hospitalization).<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722003324_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>All functioning indices were significantly associated with general psychopathology, but more complex levels provided significant incremental validity. The optimal level of complexity varied across functioning indices, suggesting that there is no single \u2018best\u2019 level for understanding relations between psychopathology and functioning.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291722003324_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>Results support the hierarchical organization of psychopathology dimensions with regard to validity considerations and downstream implications for applied assessment. It would be fruitful to develop and implement measurement of these dimensions at the appropriate level for the purpose at hand.

settings.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0033291722003324","type":"journal-article","created":{"date-parts":[[2022,11,29]],"date-time":"2022-11-29T08:30:14Z","timestamp":1669710614000},"page":"6142-6149","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["Validation
